Sapphire is the blue variety of corundum, one of the hardest gemstones on Earth at 9 on the Mohs scale — tough enough for daily-wear rings and heirloom jewelry. While royal blue remains the classic choice, natural sapphires also occur in violet, green, yellow and parti-color shades, each with its own character. Historic sources include Sri Lanka, Madagascar and Southeast Asia; Cambodia itself has a long sapphire-mining heritage around Pailin.Every sapphire sold by GEMIC Institute is a natural, individually photographed and filmed stone — what you see in the listing is the exact gem you receive. Our in-house accredited gemologists test each sapphire in our Siem Reap laboratory and deliver it with its identification certificate stating species, treatment status, weight and dimensions.Each piece in this collection is one of a kind. Orders ship worldwide with tracked delivery, and every purchase is covered by our 30-day inspection period. If you are searching for a specific size, origin or shade of natural sapphire, contact our gemologists — our gem hunting service can source it for you.
